\section{Sampling}
	When going from an analog signal to a digital signal (ADC). We need to convert the signal from a continuous signal to a discrete signal this is done through sampling. 
	Sampling is where extract a sample of the digital sound normally a second, and rates the sample of a signal.
\section{Sampling Rate}
	Is the rate a signal is being measured in a given sample. The unit of sampling rate is Hertz (Hz). Since Hz is defined by cycles over a second.
